Patented July 1%, 192,2,

Application filed June 15, 1920. Serial No. 389,166.

T 0 all to 710m it may concern 'Be it known that 1, ANDREW Knnnnonr, a citizen of the United Estates of America, residing at Cleveland, in the county of Guy ahoga and State of Ohio, have invented new and useful Improvements in Auto Theft Protection, of which the following is a specification.

This invention relates to improvements in switches especially adapted for controlling the ignition circuit of the engines of motor operated vehicles.

Another object of the invention is the provision of a. circuit closing switch which is operated after the manner of a combination lock, so that only persons familiar with the combination may operate the switch and theft of the vehicle thereby be prevented.

Other objects and advantages of the invention will appear as the following description is read in connection with the accompanying drawings.

In the drawings Figure 1 is an elevation of the invention.

Figure 2 is a plan view of the same.

Figure 3 is a central vertical sectional view.

Figure 4 is a detailed plan view of the base.

Figures 5 and 6 are plan views of the insulating disk.

Figure 7 is a detail sectional view showing by dotted lines the action of the spring actuated locking means.

Referring specifically to the drawings,

. wherein like characters of reference denote vided with a nut 16 for contact with the underside of the base 10.'

The sections of the rod 14- and 15 are joined together by a bowed spring 17, one

section of the spring being rigidly secured to the section 14 and the other section of the spring being swiveled to one end of the section 15, while the opposite end of the last mentioned section is provided with a ing 21 th ough which the member 19 forced by the action of the spring 17. The tension of this spring is adjustable by moving the section 15 of the rod longitudinally of the sleeve and for this purpose the rod is provided with threads which engage the upper threaded end of the sleeve.20.

Surrounding the sleeve 20 is a disk 23 which is formed of insulating material and is provided with an opening for the passage of said sleeve, while connecting with this opening is a notch 24. The disk 23 is provided upon itsupper surface with a metallic ring 25 which is provided with indicia 26 shown as numbers arranged in multiples of 5. The edge of the ring 25 is serrated so that it may be easily revolved about the sleeve 20.

Also mounted upon the sleeve 20 is a disk 2", which like the disk 23 is formed of insulating material and provided with a central opening for the passage of the sleeve and. is further provided with a notch 28. The sleeve 27 is also provided with a metallic ring 29 having indicia 30, in. the form of alphabetically arranged letters. It might be here stated that the indicia on both the disk 23 and the disk 27 is adjustable, that is the numbers and letters are carried by separate removable sections so that their relation with the notches 24 and 28 may be varied. The disk 27 is also provided with serrations around its edge.

Contacting with the upper surface of the disk 27 is a serrated retaining ring 31 which may be threaded or otherwise engaged with the sleeve 20 and acts to hold the various parts of the switch in assembled position.

In the use of the invention, the plate 11 is connected with a conductor which connects with a magneto. a. binding screw 32 being provided for that purpose, while the plate 12 is provided with a binding screw 33 for connection with a wire to the battery.

The plate 13 is suitably connected with the circuit breaker through which the current is conducted to the spark plugs in the usual manner. Normally the member 19 is held by the action of the spring 17 in contact with the inner periphery of the openings of the disks 23 and 27 but when these disks are rotated to align the notches 24: and 28 with the spaces between the plate 13 and the plates 11 or 12, the spring 17 will act to force the member 19 outward to bridge these spaces and complete the circuit through the magneto or the battery as the case might be.

The invention is susceptible of various changes in its form. proportions and minor details of construction, and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention what is claimed is 1. Aswitch comprising a base, spaced. contact plates carried thereby, said plates including a pair of opposed semi-circular members one of said members being adapted to define separate contacts each having one end spaced from the ends of the other semicircular member a switch closing member adapted to bridge the space between-the contact plates, rotatable disks for normally holding the switch closing member in inactive position andmeans whereby the disks may be rotated to release the member to bridge the space between the contact plates and selectively close a circuit.

2. A switch comprising a base, spaced contact plates carried thereby, a spring actuated member adapted to bridge the space between said contacts to close the switch, said member including a radially movable block,

rotatably mounted disks, alongitudinally movable'member and. means connecting the block and longitudinally movable member for moving the block, rotatable means for holding the block in an inactive position and means whereby the disks may be rotated to release the block.

3. A switch comprising a base, spaced moving the latter and means whereby the disks may be rotated to release the block.

In testimony whereof I afiix my signature.

ANDREW KENDECHY.
